Patients will be recruited to wear a outpatient mobile cardiac monitoring device for detection of atrial fibrillation in patients with a history of stroke of known case. Their are not study treatments or interventions, this is an observational trial. Eligible patients must be >50 years old, have a history of ischemic stroke or transient ischemic attack with a documented brain infarction within the prior 12 months. If patients are on anticoagulation therapies, they are eligible for enrollment if the long-term strategy for stroke prevention is anti-platelet therapy and not the oral anti-coagulant itself. Patients must not have an detection of AF and then must successfully activate the lifeStar device for enrollment. At the end of three weeks, the LifeStar device will be over-read and scored for the presence of AF and other clinically significant arrhythmias by the study electrophysiologist, who will determine the occurrence and burden of AF.

Non-Probability Sample

Study Population

Patients with history of stroke of known mechanism age greater than 50

Patient does not merit indefinite oral anticoagulation. (Patients requiring temporary OAC for purposes other than recurrent stroke prevention, such as treatment of a deep venous thrombosis, are eligible for enrollment if the long-term secondary stroke preventive strategy is anti-platelet therapy and not OAC).

Stroke mechanism is determined to be lacunar stroke, large vessel intracranial atherosclerosis, large vessel extracranial atherosclerosis, or a combination thereof.

Patient has been evaluated with at least a 12 lead EKG and at least one day of in-patient or out-patient cardiac telemetry, with no detection of AF or atrial flutter.

Patient has indefinite contra-indication to OAC. (Patients with temporary ineligibility for OAC, for example due to the need for invasive medical procedures or large acute brain infarction, are eligible for enrollment).

Stroke due to known cause not listed in inclusion criterion 4.

Cardioembolic stroke.

Inability to comply with LifeStar ACT monitoring regimen.
